Does anybody make a wireless system for converting a
single light switch to multiple light switch?

Problem: have a single light switch located in the most
obnoxious location, some idiot laid out the switch
locations. Want to have TWO controls of these lights,
with the controls mounted in more 'appropriate' places.
Solution: a ?? that mounts behind the original switch
with built in receiver, plus two wireless transmitters
[or three] that toggle the light setting. The wireless
controllers need only be as large as the wireless
doorlock controllers on your car keys. Each could easily
mount in the selected locations with a low profile to
blend in, looking like regular, wired switches.

Anybody make these things?

X10.com has lots of stuff like that. The only caveat is to watch out for
flourescent lites; they take special controls. I have a lot of X10 stull
around the house and love it!

There are loads of caveats with x10.

- It works for some, not for others. The X10 communications protocol is crap
so interference in some homes causes "issues". There are problems crossing
transformer (except when you don't want it to), though there are fixes for
this. However, if it works at all it's usually fairly reliable. It's
possible to get interference from neighbors.

- The hardware is cheap, in every sense of the word.

- Some X10 (older, primarily) stuff is very sensitive to transients. A blown
out light bulb is enough to take some switches out.

- X10.com is one of the worst spammers on the planet. Once they have your
email address, they'll keep your inbox full. Deal with them with this in
mind.

All that said, X10 does have its benefits and no one has done a "better" job
in 30ish years. BTW, Leviton makes X10 compatible devices. Leviton is higher
up the food chain (better products but with a price to go with it) but still
has the reliability issues.
